[Dovecot] Changing pop3_uidl_format
by Jeff Simmons 05 Oct '05

05 Oct '05

I recently set up an OpenBSD - Dovecot mail server for a client. Naturally (according to Murphy's Law) they want to use Outlook 2003, pop3s, and leave messages on the server. And just as naturally, the UIDLs don't seem to be working, and when they download mail, they get EVERY email stored on the server, not just the new ones. Other than switching them over to IMAP, I found the following in the Wiki documentation: #POP3 UIDL format to use. You can use following variables: # %v - Mailbox UIDVALIDITY # %u - Mail UID # %m - MD5 sum of the mailbox headers in hex (mbox only) # %f - filename (maildir only) #If you want UIDL compatibility with other POP3 servers, use: # UW's ipop3d : %08Xv%08Xu # Courier version 0 : %f # Courier version 1 : %u # Courier version 2 : %v-%u # Cyrus (<= 2.1.3) : %u # Cyrus (>= 2.1.4) : %v.%u #Note that Outlook 2003 seems to have problems with %v.%u format which is #Dovecot's default, so if you're building a new server it would be a good #idea to change this. %08Xu%08Xv should be pretty fail-safe. pop3_uidl_format = %v.%u So my question is, what happens if I just change pop3_uidl_format to %08Xu%08Xv and restart the server? Will it just change things over to the way I want them, or will it blow up all the existing mail already being stored there? Inquiring minds want to know. Thanks for any help you can provide. -- Jeff Simmons jsimmons(a)goblin.punk.net Simmons Consulting - Network Engineering, Administration, Security "It was on fire when I got here."

[Dovecot] using local-part delimiters in LDA delivery?
by OpenMacNews 03 Oct '05

03 Oct '05

hi all, i've exim 4.53RC2 + dovecot-cvs on OSX 10.4.2. i'm working on implementing recipient-delimiters for delivery from exim to a user's imap store using dovecot's cvs-lda. reading on the wiki (Jakob's latest comments?): " ... the part after the delimiter is passed to the lda as an additional parameter. so dovecot-lda should handle that parameter and leave the separator handling to the MTA. The MTA has to handle it anyway." it looks likes it's possible ... with appropriate changes in exim to my router: dovecot_localuser: driver = accept domains = +local_domains local_part_suffix = +* local_part_suffix_optional transport = dovecot_lda and transport: dovecot_lda: driver = pipe command = /.../deliver \ -c /.../dovecot-deliver.conf \ -d $local_part@$domain message_prefix = "" message_suffix = "" delivery_date_add envelope_to_add return_path_add log_output user = MY_MAIL_USER i'd like to be able to build delivery conditions in dovecot so that, e.g. mail to: bob(a)mydomain.com is delivered to "bob"'s default INBOX. but, mail to: bob+spam(a)mydomain.com is delivered to any specified (either a server-wide common relative path, or a user-specified) SUBFOLDER, say "bob/INBOX/.../.../spam_to_look_at" defined by a dovecot-rule invoked by the delimiter "spam" ... this is a little different than the approach Mark mentioned of delivering directly to folder_name specified by the local-part-after-delimiter ... questions: (1) until the two conf files merge, i'm guessing there needs to be some conditional logic in dovecot-deliver.conf rather than in dovecot.conf. correct? or should i be thinking SIEVE rules? (2) exactly WHAT "additional part" do i grab in dovecot? thx! richard

[Dovecot] Using procmail with virtual users...
by Arnaud Guiton 01 Oct '05

01 Oct '05

Hello all, I've a working dovecot installation on my machine, using exim3, virtual users and maildirs. I would like to add procmailrc rules for these (virtual) users, but i've not succeeded with that. The authentication is done with a passwd-file looking like this : testuser:password:uid:gid::/home/mail/testuser::chroot:maildir:/home/mail/testuser/Maildir/ i've put .procmailrc files in /home/mail/testuser/.procmailrc, but it this not taken into account, because the MTA never calls the procmail router as it resides after the dovecot one. How is the proper way of using procmail with virtual user (and is it at least possible) ? Thanks, -- Arnaud

[Dovecot] Red Hat ES 4 - dovecot-auth: Unknown password scheme SMD5
by mel llaguno 01 Oct '05

01 Oct '05

I have a couple of questions regarding the default dovecot packaged with RedHat ES 4. The dovecot version is 0.99.11-2.EL4.1 which I assume is considerably behind the current stable version of 0.99.14. Is it the fact that I am using an older version of dovecot that SSHA passwords in an openldap directory are not recognized and give the following error: dovecot-auth: Unknown password scheme SMD5 ? LDAP is working as expected for NFS maildirs. I have dovecot 0.99.13 working on fedora core 3, but the stability of fedora leaves much to be desired and would like to get a stable, low maintenance install of dovecot on an enterprise supported linux. Redhat does not have packages for 0.99.14 and I would rather compile from source if possible. I've specified --with-ldap as part of the configure script, but am wondering if there is anything more to add to support SSHA passwords. Until dovecot 1.0 is proven in the field, it is not a consideration for the production environment this server is being used for. Any help with this matter would be greatly appreciated. TIA, Mel Llaguno

[Dovecot] Can't connect to auth server at default: Connection refused
by Chris Wakelin 30 Sep '05

30 Sep '05

We've being running with Dovecot 1.0-stable since Tuesday, and on the whole it's gone very well (meaning nobody's noticed!). My best estimate is we're using half the disk accesses and 2/3 the CPU of UW-IMAP/Qpopper. We've quite a mixture of error messages in the logs, the most worrying of which is that several times we've had a few seconds of "xxx-login: Can't connect to auth server at default: Connection refused" (where xxx is pop or imap). It seems to sort itself out shortly afterwards. We're using userdb=passwd, passdb=passwd (authenticating via NIS). From Tuesday we'll be using passdb=pam (pam_ldap to Active Directory). My first guess is that some dovecot-auth process stops responding and gets killed off. Is this right? Other errors we're seeing include 1) pread_full() failed with mbox file /export/mail/c/37/sau04djp/INBOX: No such file or directory (when there is!) 2) mbox sync: UID inserted in the middle of mailbox (especially with .prayer folders - configuration folders for our Webmail) 3) file mbox-lock.c: line 505 (mbox_lock): assertion failed: (lock_type == F_RDLCK || ibox->mbox_lock_type != F_RDLCK) presumably some of these are fixed in alpha2.
